Metal mesh plastic composite pipe winded with reinforced structure and preparation method thereof

Abstract

The invention relates to a wire mesh-plastic composited tube twined with reinforcing tape structure and the preparation method. The composited tube is formed by the combination of an inner layer blank pipe (1), a twined tape reinforcing body (2) and an outer layer pipe (3). The twined tape reinforcing body (2) is of reinforcing structure formed by cross twining n layers of twined tapes round the inner blank pipe layer, wherein, the n is a natural number more than or equal to two. The preparation method comprises the prefabrication of the twined tape and the preparation of the composited tube. The preparation of the composited tube comprises the following processes: a plastic inner layer blank pipe is first extruded. Then the prefabricated tape is cross twined round the inner layer blank pipe and the twined tape reinforcing body is heated with a high frequency heating ring. In the end, a layer of plastic is extruded to cover over the twined tape reinforcing body. The invention avoids uneven distribution of twined wire owing to self stress of the wire and the processing of an outer layer plastic pipe, improves the security of the composited tube, enhances the combining strength of the inner layer blank pipe, the twined tape reinforcing body and the outer layer pipe and the loading capacity of the multiple-unit tube.

Description

technical field [0001] The invention relates to a steel wire mesh plastic composite pipe, in particular to a steel wire mesh plastic composite pipe with a winding tape reinforcement structure and a preparation method thereof. It belongs to the technical field of pipes and fittings. Background technique [0002] The development and promotion of plastic pipes have been in use for decades. Plastic pipes have been widely used due to their corrosion resistance, wear resistance, good hygiene, good circulation, energy saving and environmental protection. But at the same time, the disadvantages of plastic pipes such as aging resistance, low strength, low service temperature, poor thermal stability and easy environmental stress cracking often limit its application field and scope. Therefore, in recent years, the improvement of the performance and structure of plastic pipes has attracted the attention of people in the industry, and a large number of steel-plastic composite pipes have...

Problems solved by technology

The uneven winding of the steel wire may also lead to the overall failure of the entire composite pipe

Therefore, the above two steel mesh reinforced composite pipes only play a role in structural reinforcement, and the reinforcing effect of the reinforcement has not been fully exerted. The reinforcement has not been integrated with the overall structure of the composite pipe, nor has it formed a composite pipe in the true sense.
